RISK OF EXPLOSIVE GASES.
a.
WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DAN-
GEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING
NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS OF
UTMOST IMPORTANCE THAT YOU FOLLOW THE INSTRUC-
TIONS EACH TIME YOU USE THE CHARGER.
b.
To reduce risk of battery explosion, follow these instructions
and those published by battery manufacturer and manufac-
turer of any equipment you intend to use in vicinity of battery.
Review cautionary markings on these products and on engine.
2. PERSONAL SAFETY PRECAUTIONS
2.1
Consider having someone close enough by to come to your aid
when you work near a lead-acid battery.
2.2
Have plenty of fresh water and soap nearby in case battery acid
contacts skin, clothing, or eyes.
2.3
Wear complete eye protection and clothing protection. Avoid
touching eyes while working near battery.
2.4
If battery acid contacts skin or clothing, wash immediately with
soap and water. If acid enters eye, immediately flood eye with
running cold water for at least 10 minutes and get medical atten-
tion immediately.
2.5
NEVER smoke or allow a spark or flame in vicinity of battery or
engine.
2.6
Be extra cautious, to reduce risk of dropping a metal tool onto
battery. It might spark or short-circuit battery or other electrical
part that may cause explosion.
2.7
Remove personal metal items such as rings, bracelets, necklaces,
and watches when working with a lead-acid battery. A lead-acid
battery can produce a short-circuit current high enough to weld
a ring or the like to metal, causing a severe burn.
Page 7
2.8
Use the charger for charging only 6V and 12V LEAD-ACID (STD,
AGM or GEL) rechargeable batteries. It is not intended to supply
power to a low voltage electrical system other than in a start-
er-motor application. Do not use battery charger for charging
dry-cell batteries that are commonly used with home appliances.
These batteries may burst and cause injury to persons and dam-
age to property.
2.9
NEVER charge a frozen battery.
3. PREPARING TO CHARGE
3.1
If necessary to remove battery from vehicle to charge, always
remove grounded terminal from battery first. Make sure all acces-
sories in the vehicle are off, so as not to cause an arc.
3.2
Be sure area around battery is well ventilated while battery is being
charged.
3.3
Clean battery terminals. Be careful to keep corrosion from com-
ing in contact with eyes.
3.4
Add distilled water in each cell until battery acid reaches level
specified by battery manufacturer. Do not overfill. For a battery
without removable cell caps, such as valve regulated lead acid
batteries, carefully follow manufacturer’s recharging instructions.
3.5
Study all battery manufacturer’s specific precautions while
charging and recommended rates of charge.
3.6
Determine voltage of battery by referring to car owner’s manual
and make sure that output voltage selector switch is set at cor-
rect voltage (if applicable). If charger has adjustable charge rate,
charge battery initially at lowest rate.

AUTOMATIC CHARGING MODE
When an automatic charge is performed, the charger switches to the
maintain mode automatically after the battery is charged. For a battery
with a starting voltage under 1 volt, use a manual charger to pre-charge
the battery for five minutes, to get additional voltage into the battery.
BAD BATTERY
If charging cannot be completed normally, the charger’s output is shut
off and the red LED will flash. Have the battery checked and replace,
if necessary.
DESULFATION MODE
If the battery is left discharged for an extended period of time, it could
become sulfated and not accept a normal charge. If the charger
detects a sulfated battery, the charger will switch to a special mode of
operation designed for such batteries. If successful, normal charging
will resume after the battery is desulfated. Desulfation could take 8-10
hours. If desulfation fails, the red LED will flash.
COMPLETION OF CHARGE
Charge completion is indicated by the green LED. When solid, the
charger has switched to the maintain mode of operation.
MAINTAIN MODE (FLOAT MODE MONITORING)
When the green LED is solid, the charger has completed charging and
started maintain mode. In this mode, the charger keeps the battery fully
charged by delivering a small current when necessary. If the charger
has to provide its maximum maintain current for a continuous 12 hour
period, it will go into abort mode (see Aborted Charge section). This is
usually caused by a drain on the battery or the battery could be bad.
Make sure there are no loads on the battery. If there are, remove them.
If there are none, have the battery checked or replaced.
Page 16
MAINTAINING A BATTERY
This unit maintains both 6 and 12 volt batteries, keeping them at full
charge. It is not recommended for industrial applications.
NOTE: The maintain mode technology allows you to safely charge
and maintain a healthy battery for extended periods of time. However,
problems with the battery, electrical problems in the vehicle, improper
connections or other unanticipated conditions could cause excessive
current draws. As such, occasionally monitoring your battery and the
charging process is required.
